Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Strongly straight, coarse, and open-grained with a uniform texture. Visible growth rings on the face grain indicating a flat-sawn or slightly rift-sawn orientation.
Color Description
Heartwood is a golden brown that has weathered into a medium-to-dark muted brown with greyish surface oxidation. It exhibits low luster due to natural oils and develops a silvery-grey patina if left untreated outdoors.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to decay, rot, and termites due to high natural oil and rubber content. Highly weather-resistant.
Common Uses
Marine decking, boat building, outdoor furniture, high-end exterior joinery, flooring, and veneers.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for genuine Burmese/Old Growth; $15.00 - $25.00 for plantation grown.
Wood Age Estimate
20-40 years based on the depth of oxidation and the weathered, slightly fibrous texture of the surface grain.
Sustainability Status
IUCN Red List: Endangered (Wild). CITES: Not listed, but Myanmar Teak is subject to international trade sanctions. FSC certified plantation teak is widely available.
Workability
Generally easy to work but high silica content causes significant blunting of cutting edges. Glues well if surface oils are wiped with solvent (acetone) before application.
Notable Features
Distinctive leather-like scent when freshly cut. Naturally oily feel. High silica content provides natural slip resistance and durability.
Finish Recommendations
Teak oil or tung oil to maintain color; marine-grade varnish or epoxy for heavy-use aquatic environments. Can be left unfinished to weather to grey.
Identification Confidence
High. The straight, coarse grain combined with the specific golden-brown weathered hue and fibrous surface texture is diagnostic of Tectona grandis.
